摘要：Flooding is one of the problems that Jakarta faces every year. To handle the issue, the government took action to build the East Flood Canal. The canal construction is expected to reduce flooding, especially in the east and north region of Jakarta. However, the construction did not make the area immediately free of flood risk. Previous study (Susanti, 2017) showed that even with the existence of the East Flood Canal, potential inundations may still happen, specifically in the Cakung Lama area. In 2017, there were still several inundation points in the Sunter area, especially in Kelapa Gading. This research aims to identify the cause of inundations in the area by evaluating channel capacity in the micro drainage system in Kelapa Gading using hydrological model HEC-RAS 4.1.0 and WinTR. The simulation results showed that several channels in the system cannot accommodate the inflow, hence causing inundation in some areas in the Kelapa Gading area. According to the simulation results, it can be concluded that the micro drainage system in Kelapa Gading is not effective to accommodate the inflow.
